Does anyone know where I can find exhaust system schematics (which pipe goes into what) for a 1978 Cadillac Deville? I currently have the tailpipe, another pipe, the muffler, and the cat but I can't seem to figure out how to hook it all up. I might buy a shop service manual but Imma put it off for a bit... Just a shot of the undercarriage of that year car would help! Is it welded or bolted?

www.gmpartsgiant.com - your car, model, system. That opens a text page. The "more info" tab opens a parts blowup keyed to the text page.

Yea, it isn't listed heh... I looked and even tried the VIN thingy, but apparently pre-1980s it was a 12 digit VIN. Any other ideas?

Go to rockauto.com, pick your car, pick exhaust, click on "info" for one of the pipes, it will open a page with the image you need. It should be pretty simple, though... y pipe to cat to mid pipe to muffler to over axle pipe to resonator to tail pipe.
